I activated a node using OTAA (deveui,appeui,appkey) and it got successfully registered. The rx and tx were working perfectly.
After 2 weeks I performed a sys factoryRESET on my node and when again I tried to do the OTAA with same (deveui,appeui,appkey) it is showing Denied. (Also, app server is showing that device is activated)
Is there a way I can re-configure this device with same (deveui,appeui,appkey). Or do I need to use this node as a new device ?
